激光雷达-1
what is LiDAR?
LiDAR is a remote detection andranging method that works much like radar, emitting infrared light pulsesinstead of radio waves andmeasuring how long they take to come back after hitting nearby objects.The time between theoutput laser pulse and the reflected pulseallowsthe LiDAR sensor tocalculate the distance to each object precisely,based on the speed of light. LiDARcaptures millions of such precise distance measurement pointseach second, from which a 3D matrix of its environment can be produced.Information on objects’ position, shape, and behavior can be obtained from this comprehensive mappingof the environment.
【激光雷达-1】Lidar是一种远程探测和测距方法，工作原理和雷达类似，发生红外光脉冲（而不是无线电波），然后测量激光到达目标返回的时间。Lidar可以根据输出激光和反射激光的时间差，利用光速就可以精确计算每个目标的距离。lidar每秒钟可以生成数百万这样精确的距离测量点，然后可以生成周边环境的3D矩阵。从这幅周边环境的匹配中，可以获取目标的位置、形状和行为。
